Improvement in surge-relievers



N. FETERS, PHQTO-LITMOGRAFHER. WASHINGTON. D c.

To all whom it may concern` "l scribed.

@Htnt @with v anatema Be it-known that I, J oHN E. JONES, of \Viretown,

p `in thc county of Ocean andState of New Jersey, have` invented a new and useful Improvement Vin Elastic Gable Apparatus;` and I do hereby declare that 4the following is a full, clear, and exact description thereof,

` 'l which willcnableothers skilledinthe art to make and use the same, reference being `had to the accompanying drawing forming part of this-specification.

-The obJect of. this invention 'is to providenmcans D for giving elasticity to chain `cables on board of ships and steamboats, designedff'or relieving the cable in `breaking the anchor ,from the ground, and in the singing of the vessel; and l 1t consists in an adjustable. i'ame,.p1`ovided with. elastic springs, so arranged as to receive the strain of the cable, and `operating as hereinafter more fully del In the accompanying drawing- Figure l represents a sectional side viewof the apparatus, connected bythe cable with `the windlass.

. Figure 2 isa front view of the apparatus, detached from thewindlassand cable. y l Similar letters of reference indicate corresponding parts.' v y .A is the windlass. l .B is the bed-plate,`which may represent the deck.

l C is the cable.

l D represents afi-ame, of iron or other suitable metal, consisting of fourluprightrods, E, attached to bascpeces F, which pieces are pivoted to base-blocks G,

as seen in fgfl, so that the frame may rock on the base-blocksand bc adjusted or adjust itself` according to the position andstrain `on the cable. p

H is apap-piece, by in'eansof which each pair ofV uprightsare connected together in one direction; and

p v Letters Patent No; 107,917, dated 00am4.1870.

The Schedule `referred. to in-.these-Letters Patent and making part of the same I is a cap-piece for each pair of uprights, 'which connectthem inv the other direction.

J J are metallic follower-blocks, ywhich slide up and down with the springson the upyights E, and which support thesaddle-rollerl, over which the cable is carried from the \vindlass, as seen `in lig. 1.

L represents rubber springs, which are slipped ontoeach ot' the rods, and bear upon hase-pieces F.

vM are stays for supporting the frame D in the proper position.

N are blocks of rubber, which are let into the base- I `blocks Gfor receiving the. base-pieces F when the frame is inclined in either direction. l

It will be seen that, when the cable is strained, either by breaking anchor from the ground or by the surging of' the yessel, the springs L will be compressed by the strain of the cable on the saddleroll K. ble to prevent all damage under such circumstances.

This is a most durable and eiiicient arrangement for the purposes intended, and its advantages will be purposes described.
